  • Resonant linearly polarized eddy current sensor
    Patent number: 8324894
    Abstract: A linearly polarized eddy current sensor including a source antenna and a parasitic antenna coupled to the source antenna, serves as a high sensitivity tool for the measurement of the surface impedance of sheet goods without requiring contact with the sample. Sheet goods can have an anisotropic, frequency-dependent surface impedance that is sensitive to minor changes in configuration of the sample. Because the electric field induced by the sensor is linearly polarized, measurement of directionally dependent sheet impedance can be achieved. The measurement is performed with the resonant device operating in resonance mode whereby the immediate proximity of the material to be measured causes damping and shifting of the coupled loop resonance. The resonant frequency of the sensor can be tuned by making changes to its geometry.
